Abstract (en)
A waveguide slot antenna having a plurality of waveguide emitters (15) which are operated in a non-resonant manner and each have two rows of slots (16) on the broad side, which are supplied by a supply waveguide (10) which is operated in a non-resonant manner. The phase shift which results because of the non-resonant dimensioning is compensated for by offsetting (20) the slots of adjacent waveguide emitters in a specific manner such that the antenna polar diagram has no squint angle in the azimuth direction. <IMAGE>
Abstract (de)
Hohlleiterschlitzantenne mit mehreren nichtresonant betriebenen Hohlleiterstrahlern (15) mit jeweils zwei Schlitzreihen (16) auf der Breitseite, die von einem nichtresonant betriebenen Speisehohlleiter (10) gespeist werden. Die sich wegen der nichtresonanten Dimensionierung ergebende Phasenverschiebung ist durch Versetzung (20) der Schlitze benachbarter Hohlleiterstrahler in bestimmter Weise kompensiert, derart, daß das Antennendiagramm keinen Schielwinkel in Azimutrichtung aufweist. <IMAGE>
